Dear All, We have a webserver on our network as a front end to our ERP system. On a few PCs running XP SP3, we have suddenly encountered an issue in that when connecting to our ERP webserver, IE6 thinks it is in the Intranet Zone and not the Trusted Site Zone. GPO looks OK and applies without error to the PC. I have checked the registry, and in both HKCU and HKLM, the web server shows as being in zone 2 i.e Trusted Sites: HKLM or HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains I have deleted the entries from the registry then done a GPUPDATE /FORCE. Again the server appears in the registry as Zone 2, but when I run IE and connect, the bottom right hand corner shows Intranet. The only thing that I am aware of that changed on the PCs is the fact that Sophos AV was installed using Sophos Enterprise Console. This is driving me mad. I stop for my 2 weeks summer holiday on Friday 23 July and I would love to have this issue resolved by then. Regards Alan
